OORP R TION P ILLINOIS APPARATUS FOR MAP DISPLAY Application filedOctober 7, 1927. Serial No. 224,650.

My invention relates in general to methods and apparatus for conveyinginformation and giving instruction through the medium of maps, chartsand the like, and more particularly to a combination moulding strip andsuspension clip structure for slidably supporting maps and charts.

An object of the invention is to provide an adjustable mounting forprincipal maps or 1g display sheets either mounted or unmounted; toprovide a mounting for minor or temporary sheets; and to provide meansby which the minor or temporary sheets may be definitely secured inproper position relatively to the principal sheets whereby the two setsof sheets may be coordinated and referred to contemporaneously. IAnother object of the invention is to pro vide a display map mouldingstrip.

A further object of the invention is to provide. a novel suspension clipadapted to be slidably and removably mounted upon my novel mouldingstrip.

In accordance with the general features of my invention, I provide asubstantially continuous wall moulding adapted to be cut to convenientlengths, together with a suspen sion device or clip of such aconstruction as to be reciprocal to the construction or form of themoulding so that it may be readily mounted upon the moulding and securedthereon against accidental displacement.

Other objects and advantages of my construction will more fully appearin the following detail description, taken in connection with theaccompanying drawing, which illustrates a single embodiment thereof, andin which:

Figure l is a fragmentary frontelevation of certain suspension elementsforming a part of my invention and illustrating it as applied to one ofthe walls of a room and representing a map suspended therefrom; I Fig. 2is a fragmentary perspective view of a portion of the moulding stripillustrating the insert therein; I

Fig. 3 is a fragmentary sectional view taken on substantially the line33 of Fig. 1; Fig. 4 is aperspective view of the suspen= sioncliplooking at it-from the front;

Fig. 5 is a perspective View of the suspension clip looking at it fromthe rear; and

. Fig. 6 is a view similar to Fig. 3 illustrating the suspension clip assupporting a map mounting of the character disclosed in my copendingapplication, Serial Number 224,651, filed Oct. 7, 1927. It is thoughtthat my novel method of con veying information will be readilyunderstood from a detail description of the apparatuses by which it maybe practiced.

Referring now to the drawing in detail, in which like characters ofreference denote similar parts throughoutthe several views: Numeral 1designates generally a channelshaped moulding strip preferably made ofthin metal and comprising a base 2 and a pair of laterally extendingsides 3-3. Formed integrally with the outer ends of the sides 7 3-3 is apair of flanges 4c and 5 disposed substantially parallel to the base 2.These flanges extend outwardly and laterally from the sides 33 andproject in opposite directions.

The channel defined by the strip 1 is filled by a stiifening'strip orinsert 6 which may be of cork, wood or analogous material of propershape and size to fill the channel of the moulding strip throughout itslength. This strip may be secured in place within the channel by meansof glue or other cementitious material. The fastening for the in sert 6is further established by the means provided for securing the strip tothe relatively stationary support or wall.

It will be noted from Fig. 3 that the outer surface of the core orinsert 6 is disposed slightly below the flanges l and 5. The insert 6 isprovided at intervals with holes 7 which are disposed in alignment withholes 7 in the base 2 of the strip. The holes in the insert 6 arepreferably countersunk, as shown in Fig. 3. Positioned in each set ofthe aligned holes 7 and 7 is a tubular eyelet 8 having outwardly flaringedges 9. It will be noted from Fig. 3 that the edges 9 of the eyelet aredisposed flush with the flanges 4 and 5 of the strip. A screw 10 ofsuflicient length to secure the strip to the relatively stationarysupport is disposed in each eyelet 8. 'Each of these screws is providedwith 4 indicated at 18.

an enlarged head 11 seated in the flared portion of the associatedeyelet. These screws not only serve as a means of securing the mouldingstrip 1 to the support or wall but, previously pointed out, at the sametime tend to air fastening the core insert 6 to the metallic strip 1.

A. moulding strip thus formed and mounted is provided with movablesuspension devices or clips formed to embrace and having slidablemovement on the moulding strip. Each of these clips may be made from ablank of thin metal and comprises a body portion 14 and inwardly turnedflanges bent back upon the body portion 14 including a top member 15turned back and downwardly flanged to ride upon the upwardly turnedflange ot' the moulding strip, and an upwardly turned flange 16 adaptedto engage the downwardly turned flange of the moulding strip.

A hook 17 is turned outwardly from the body portion 14. and is disposedat substantially a. right angle to the portion l i, as Attention isdirected to the fact that. the flange 16 comparatively shorter in lengththan the flange for a purpose which will become more apparenthereinafter. Extending from the body portion 15 adjacent the flange 16is an oflset member 20 including a downwardly projecting wall fender 21.

The lower flange 5 of the moulding strip is provided with spaced notches23, each of which is of such a width as to receive the lower andrelatively short flange 16 of the suspension clip. It will thus beevident that when the suspension clip is attached by means of its owndownwardly turned flange 15 to the upwardly turned flange i of themoulding strip, the flange 16 may enter one of the notches 23 and may bethus readily engaged by lateral movement in either direction with thelower flange 5 of the strip. This arrangement insures against theaccidental displacement of the suspension clip relative- 1y to themoulding strip.

After a pair of the suspension clips have been slidably mounted upon thestrip 1, they may be spaced a given distance apart so as to accommodateand support a device such as the map 25, shown in Figs. 1 and T his mapincludes eyelet lugs 26 adapted to be hung on the hooks 17 of thesuspension clips. It will be noted that the map stick 28 of the map isadapted to abut the fender plate 21 of each or the suspension clips, asshown in Fig. 3. This tender plate 21. due to its offset positionrelative to the plane of the body portion ll of the clip, serves tomaintain the map away from the wall, thus preventing the map from beingsoiled by contact therewith. Moreover, should the map he posltioned soas to be drawn down over the front of a blackboard, by my spacing itfrom the surface of the blackboard, it will follow that any chalk dataon the board will not be erased or marred by the rear of the map cominginto contact with the board.

In Fig. 6, I have illustrated my novel map supporting structure assupporting a map mounting 30 of the construction disclosed in myco-pending application, Serial Number 224,651, filed Oct. 7, 1927 Thismounting as disclosed in my co-pending application comprises a pair ofspaced brackets secured to a metallic spacing strip 71. The upper edgeof the spacing strip 71 is provided with spaced openings 74 forreceiving the hooks 17 of the suspension clips. From the foregoing, itwill be readily apparent that not only can my novel suspension clips beutilized to support a map or chart such as the map but they may also beused to support a mounted map unit including a spring shade rollermounting such as indicated at 30, and suspended, as shown in Fig. 6, sothat the lower port-ion of the roller mounting will bear against thefender member 26 and hold the spring roller and the dogs thereo'l inoperative position.

Now it frequently happens in the use ol" charts and maps that temporaryor auxiliary sheets of data are associated with the map so as to aid inthe explanation of the same. By providing the moulding strip with insert(5 of cork or other material which will readily receive and firmly holda thumb tack, these auxiliary sheets of data may be positioned andsupported in proximity to the principal sheets or map. In Fig. 1 isillustrated an auxiliary sheet 30 for additional related matter which ispositioned adjacent to the map 25 and secured to the cork 6 of themoulding strip by means of thumb tacks 31. Due to the proximity of themap 25 and the sheet 30, it will be evident that they may be studied andvisualized together.

Now I desire it understood that, although I have illustrated anddescribed my invention in detail, the invention is not to be thuslimited, but only in so far as defined by the scope and spirit of theappended claims.
